bug: IonModal focus trap does not allow other components to overlay

• I have searched for existing issues that already report this problem, without success.

Ionic Framework Version

v7.x

Current Behavior

When using other components that utilize the Angular CDK or similar methods to present content in an overlay (for example, a select, date, or color picker) within an Ionic modal, this overlay is affected by the Ionic modal's focus. This seems to be related to the class: "ion-disable-focus-trap".

Is there a way to disable this requirement when starting an Ionic modal via a declarative element or via ModalController?

I found a post on Ionic Forum: https://forum.ionicframework.com/t/work-around-for-ionic-modal-focus-trapping/216633/6 where a user described a similar issue and other user sugested a hack:

Copy code
<ion-modal #myModal>
  <ng-template>
    <ion-content>
      <mbsc-datepicker
                    (onOpen)="myModal.cssClass = 'ion-disable-focus-trap'"
                     (onClose)="myModal.cssClass = ''">
       </mbsc-datepicker>
    </ion-content>
  </ng-template>
</ion-modal>

This helps, but not gracefully, as this code has to be duplicated in all Ionic modals where there are other components that utilize the Angular CDK overlays or similar.

Using ModalController and passing a function to the component, something similar to this would be necessary:

onOpen(open: any) {
       this.ModalController.getTop().then(modal => modal?.classList.toggle('ion-disable-focus-trap', open));
}

Expected Behavior

Let user define the modal focus behavior or disable focus trap it not currently necessary ionic framework.

Steps to Reproduce

1. clone the testing repo
2. npm install
3. ionic serve
4. open the modal
5. try to interact with the select components
